CHAPTER 106 — The File Class

Often a program operates on a disk file as a whole ― renames it, checks if it exists, deletes it, or alters its properties. These operations are performed by using the methods of the class File. This class is also used for working with disk directories. (Directories are sometimes called "folders".)

Using the File class will improve programs that read or write disk files.
